When you do, let us know if you have discovered the wonderful world of a stuck case. While you are experimenting, put a little dab of the Petroleum Jelly in a primer to see if it kills it. Lastly, you may as well report back to us what way you discovered as to how to remove the PJ from the cases after sizing. I love it when some guy assumes all the risk of experimenting and I get the benefits.

Give the guy some credit for at least asking the question. There are kinder ways to suggest that it may not be an equivalent substitute.
